I know how this feels, I often find myself thinking of loads of things I want to say right after a session and wishing I could tell my therapist those things there and then but unfortunately we can't.

I find that by writing down what happened in the session and anything that comes into my head after the session (that I wish I had said) helps me get it off my chest and feel a bit more relaxed about it. I then also know I will remember it if I want to take it into the following session. You may benefit from this type of journal writing?

I also find after a session, emotions tend to be high and sometimes its best to wait out the feelings until the following day at least and if by then you still feel the extreme need to contact your therapist then, then at least you have given it some time.

I know its hard to feel the way you do, I understand!
